Abstract (en)
[origin: EP3421816A1] A centrifugal compressor 1 of the present invention includes: an oil heater 60 configured to adjust temperature of environment by a heat medium; a heat shield 11 that is provided between a suction flow path 18 and the oil heater 60 and defines, with a diaphragm 3, the suction flow path 18 introducing a fluid F to an impeller 9; and straightening vanes 3B provided in the suction flow path 18 and configured to straighten the fluid F flowing through the suction flow path 18. Top ends of the straightening vanes 3B are inserted into interference maintaining grooves 45 in the heat shield 11, and even if thermal deformation occurs and the straightening vanes 3B are displaced most in a direction X away from the heat shield 11, the top ends of the straightening vanes 3B stay in the interference maintaining grooves 45 in the heat shield 11.
